You can delete any saved cohort executions that you no longer need to analyze.
To delete such cohort executions:
Click Actions > Campaigns+.
Edit the campaign and go to the Destination section
Enable the Purge cohort executions before toggle bar.
This option permanently deletes data for all prior cohort executions of the selected campaign based on the specified date and time.
Save the campaign.
Important
This is an irreversible action. Once you save a campaign, the system removes cohort data before the specified date and time from Metrics and Interactive Queries during the next pipeline run. To prevent future executions of this campaign to be saved as cohorts, disable the Cohort Analysis toggle bar.
